' My invention relates to cap. fastening means for preserving jars andits objects are to provide fastening means of simple and 7 strongconstruction with which a jar may be quickly sealed and openechwithwhich any degree of sealing pressure may be easily api plied withoutdanger ofthe parts slipping .out of place, and which will maintain thesea-ling pressure on the cap indefinitely.

These objects, and other advantageous ends which willbe describedhereinafter, I

- in attached position, and

Figure 5 a fragmentary section on line 55 of Figure 4. 7

Referring to the drawings. 1 indicates a jar reinforced at its edge by athickened part 2; 3 a pair of lugs on the thickened part having verticalgrooves 4 therein. their under faces 5' inclined outwardly anddownwardlyand their front faces 6 inclined upwardly and inwardly; 7 ayoke of spring metal having T-shaped ends 8 adapted to slide down vtheinclined front faces 6 to fit intogrooves 4"and engage the inclinedunder faces-5; 9' -lips on the T-shaped ends by which they may begripped and sprung apart; 10 a socket in the center of the yoke forreceiving and hold-' ing a nut 11 12 a thumb screw threaded in nut 11and arranged to take into a hollow in a raised part 13 on a capld"; 15an annular tenon adaptedto forcea gasket 16 into an annular mortise 17in thickened part2 when pressure is applied byscrew 12 .to make a seal.7

To seal the jar, gasket 16 is placed on mortise 17 and cap 14 placed onthe gasket.

is within the hollow of raised part 13. By

Yoke 7, which is of spring metal, is slipped into place by sliding theT-shaped ends 8 from the position shown in Figure 3 down' the inclinedside facesfi until the. T-shaped ends snap into engagement with theinclined under faces 5 of the lugs as shown in Flgure 4. Screw 12 isthen turned untilits end further ;;tur'ning thefscrew any. degree ofsealing pressure may be placedpn gasket 16. Oneor two turns of the screw1s sufficient to produce a sealing pressure for ordinary :purposes. g i

the ends of the yoke 7 sprung apart by gripping the lips 9 withthefingers and pulling the T-shaped ends apart so that they clear the lugs8, after which the yoke maybe removed and'cap 14 lifted off thejar. I

It will be seen that with the fastening means set forth, jars may beeasily and quickly sealed or opened by a child or other person of equalstrength; inc-lined faces 5 will prevent the ends 8 of the yoke fromspringing apart while sealing the jar; the grooves 4 in conjunction withthe inclined faces 5 'prevent the yoke from being accidentally knockedout of sealing position and socket 10 forms aneificient holder for nut11 on ayoke made of light spring metal.

While I have described my invention as taking a particular form, it willbeunder-,

stood that'the various parts maybe changed at liberty to make suchchanges and altera-.

tions as fairly come within the scope of th ppended claims.

Having thus described vmy invention,v

whatI claim as new and desire to secure by Letters Patent'is e 1. Capfastening means for jarsincluding. lugs secured to the opposite sides ofthe jar haying vertical groovcs'and inclined under Y faces; saidlugshaving front faces inclining j towardthe top of the ar; a yokehaving T- shaped ends adapted to fit in the grooves and engage theinclined underfaces; threaded means in the'yoke, and means engagingtherewith for holding the cap to thejar.

' 2. Cap fastening means for jars including lugs secured'to the oppositesidesfof the jar and havlng vertical grooves, inclined under faces andinclined front faces;.a yoke having T-shaped ends adapted -to slidealong and a nut secured in'the yoke, and a bolt threaded to the nut forholding the cap to the jar under a desired pressure.

3. Cap'fastening means for jars including grooved lugs at opposite sidesof the jar having inclinedundei' faces; a yoke having 'Tshapedendsadapted to fit in the grooves and under the lugs and a socket hetvieen' the end 'ki hutseCu-red 'in the soeket, escrow ing said grooves.

4. Cap fastening ii'ieatns for ja rs including grooved lugs at oppositesides of the ar hav ng inclined SldB faces and "inclined 11nder faces;2iyoke nade o'i' spring'metal 1'einforeed to effect added resistancethereof in one ditection'withoutdiminishing resili- 'ency 1n the otherdlrection; and having T- shaped ends. adapted to fit in the groovesend'under the lugs and lips extending from the T-shaped ends wherebysaidends may be gripped and sprung apart, a screw in the yoke forholding the cap to the jar; said inelined front faces effectivelypreventing said yoke from slipping from said unde1faces;

I11 testimony whereof I have signed my name to this specification.
